uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+Subject: [PATCH] adjust socket paths for nixos
+
+The original unscd would crash, because it is not allowed to create its
+legacy socket at /var/run/.nscd_socket.
+
+This socket is only required for very old glibc versions, but removing it
+is currently non-trivial, so we just move it somewhere, where it is
+allowed to be created. A patch has been submitted upstream to make this
+hack unnecessary.
+
+Also change /var/run to /run, since we shouldn't be using /var/run
+anymore.
